We get a lot of brutally cold days too, but normally the temp goes up every once in a while to warm you up, with the sun enhancing your mood. It's felt like we had very few days like that this year and I guess that's what's made it so tough. It's gotten to -20 numerous times with windchill bringing it down to -45, whatever "feels like" temperature means. (The way it affects your skin, I suppose.)
